Specification of Letters Patent.

Application filed March 17, 1919; Serial No. 283,219.

To all whom it may concern:

Be it known that I, HARTLEY BAKER, a

v useful Improvements in Pump Drive Apparatus; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a mechanism for driving the pumps of a steam automobile or similar machine, and aims to provide a novel and improved pump drive apparatus driven from the steam engine and including novel means for driving and operating the pumps for pumping the water for the boilers, kerosene or other fuel to the burners, lubricant to the bearings of the engine and other parts, or the like.

A further object is the provision of novel means for driving the pump mechanism, or

the like, from the crank shaft of the engine,

which can not only be used for driving pumps, but can also be used for operating other devices.

A still further object is the provision of a novel and improved mechanism for the pumps, providing a practical and efficient construction. v

It is also the object of the invention to provide such an apparatus which will be comparatively simple and compact in constructiomand which will operate efficiently without being apt to get out of order.

With the foregoing and other objects 1n View which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

, between.

The invention is illustrated in the accompanying drawings, wherein Figure 'lis a plan View of the engine and pump casing showing the connection there- Figure 2 is an enlarged plan view of the engine, portions being broken away.

Figure3 is an enlarged sectional detail showing the connection ofthe driving gearing with the crank shaft of the engine.

- Figure 4 is a plan view of the pump mechanism, with the cover of the casingremoved,

and portions being shown in section.-

- Figure 5 is a side elevation of said mechanism-showing thecasing and other portions in section.

Figure 6 is a side elevation showing a modified driving mechanism, operated by the engine crank shaft, for obtaining a re ciprocatory instead of a rotary motion.

A conventional style of automobile steam engine is shownin Figures 1 and 2, embodying the cylinders 1 having the piston rods :2 extending rearwardly into the crank casing 3 in which the crank shaft 4 is mounted for rotation, the cranks thereof being connected by the connecting rods 5 with the piston rods 2. A! gear 6 of the differential 7 engages a gear 8 driven by and mounted on the crankshaft for driving the rear axle sections to propel the vehicle.

In carrying out the invention, andto provide means for driving the pump or other mechanism from the crank shaft 4, one end of said crank shaft has a stub 9 extending therefrom to enable a pinion 10 to be keyed orotherwise secured thereon, and a gear wheel 11 meshes with the pinion- 10 and is rotated at a slowervelocity so that the pump or other mechanism will be driven at a sufiic-iently slower speed than the engine crank shaft, in order that the proper speed reduction is provided. The gear wheel 11 is keyed on a short shaft 12 journaled, preferably by means of roller hearings, in standards or brackets 13 and 1-fwithin the easing 3. The standard or bracket 14 is of angular form to also constitute a bearing for the rear end of a longitudinal power transmitting shaft 15, and meshing'bevel gears 16 are secured to the shafts 12 and 15 within the angle of the standard or bracket 14 to transmit the power from the gear wheel 11 and shaft 12 to the shaft15. This shaft 15 extends forwardly through a suitable packing '17 in the forward end of the casing 3, and the forward end of the Patented June 1922.

shaft 15'is grooved "longitudinally as at [motion for operating the plot specmlmeans for ad ustment is provided.

-' The u'm' mechanism as shown in hi 7 b ures 4 and 5, includes a bevel ear 23 secured on the forward end of the shaft 21 withinthe rear end of the casing 22 and meshing with a. bevel gear 24 keyed on a short transverse crank shaft 25 journaled.

,within a bearing 26 within the casing 22 that houses the pump mechanism. This shaft 25 is provided with a crank 27, one

arm of which is secured to the shaft 25 and the other arm free.

A connecting rod 23 connects thecrank 27 with the cross head 29 movable longitudinally within'the casing 22.

As shown, there are two water pumps for supplying water to the boiler, and include ithe opposite longitudinal water cylinders 30 having suitable check valve inlets and outlets 31 at their'opposite ends, and plunger rods 32 projects slid-ably into the adjacent open'ends of the cylinders, which are provided with suitable packing 33 to embrace s'aid rods and prevent leakage. The ad 'jacent ends of the plunger rods 32 are screwed into the cross head 29 in alinement, and lock nuts 35 are threaded on the rods 32 to bear against said cross head to hold said'rods in their adjusted position. It will be notedthat when the cross head reciprocates, the plunger rods 32 operate oppositely in the two cylinders 30, one plunger rod entering-one cylinder to displace the water,

and the other plunger rod beingwithdrawn from its cylinder to draw the water into the last named cylinder.

This provides for double action to supply a constant stream of water to the boiler when needed. A kerosene or fuel pump is shown as being located at one side of thatwater pump furthest away from the drive shaft '21, and includes a longitudinal cylinder 36 having a suitable check valved inlet and outlet for the fuel, with a plunger rod 38 silnilarto the rod 32 and packing 39 for said rod. The rod 33 is screwed into the cross head 29 and has a lock nut 40 thereon bearing against said cross head to prevent loosening of the rod,

The plunger 33 in working within the cylindei 36 will draw the kerosene or other fuel into said cylinder and then displace same as the rod reciprocates.

An oil or lubricant pump is also provided,

' *including a cylinder ll having suitable inlet and outlet means 42, and a plunger rod 4-3 working within the cylinder through suitable packing l l. In addition to the crank rer rod Thus, the free arm of the crank 27 is provided with a longitudinal slot '45 in which an adjustable wrist pin 46 is mounted for radial adjustment relatively to "the'a'xis 'of the crank shaft 25, and a connecting rod 47 connects the wrist pin 46 and rod 43. The wrist pin as is in the form of a bolt having its head seated in the slot 45, and when the bolt is tightened, it will retain its adjusted position. By loosening the bolt, it can be adjusted to regulate the throw of the plunger rod 43, so that the lubricant will be fed at the desired flow, such flow being increased and decreased by adjusting the wrist pin 46 further away from or closer to the axis of the crank shaft. All of the pumps are thus operated from the same crank 27, with provision made for the adjustment of the lubricant pump.

In operation, the shaft 15 imparts-movement to the crank shaft 25 of the pump mechanism, which is operated at a slower speed than the engine, in order to provide a smooth action of the pumps. The crank 27 reciprocates the cross head 29 to operate the water and kerosene or fuel pumps, while the lubricant pump is operated from the adjust-able wrist pin 46 carried by the crank 27.

In the modification shown in Figure 6, a reciprocatory motion instead of a rotary motion of the pow-er transmitting'mechanism is shown. Thus, the shaft 12 of the gear wheel 11 has a crank 50 connected'by a connecting rod 51 with a cross head 52 slidable within guides 53 within the crank casing 3, and a sliding rod 54 extends forwardly from the cross head 52 througha packing 55 in the front wall of the casing 3, and can be connected directly to the cross head 29 or other reciprocatory part of the pump mechanism. This modification employs the same manner of connecting the driving means with the crank shaft of the engine,

but does not have the advantages of the mechamsm shown in Figures 4 and'5 including the crank shaft 25 and manner of connecting same with the pumps.

Having thus described the invention,'what is claimed as new is A pumping apparatus for several different fluids comprising a pair of opposite pump cylinders, a cross head between said cylinders, individual plunger rods connected to said cross heads and extending in opposite directions and working in said cylinders, a third cylinder atone side ofone of the aforesaid cylinders, a. plunger rod working inthe third cylinder, said crosshead extending to one side from the first-named plunger rods, the last named plunger rod becylinder located at the corresponding side of the other of'the first-named cylinders, a crank shaft mounted'for rotation adjacent to the last-named cylinder of the pair and having a crank at one end with one arm mg connected to said cross head, a fourth' free, a connecting rod connecting said crank In testimony whereof I have signed my and cross head and Working between the name to this spec1fication in the presence of last-named cylinder of the pair and the two subscribing Witnesses.
